This class produces a special form of reversed tokens, suitable for
better handling of leading wildcards. Tokens from the input TokenStream
are reversed and prepended with a special "reversed" marker character.
If withOriginal argument is true then first the
original token is returned, and then the reversed token (with
positionIncrement == 0) is returned. Otherwise only reversed
tokens are returned.

Note: this filter doubles the number of tokens in the input stream when
withOriginal == true, which proportionally increases the size
of postings and term dictionary in the index.
